Synthesis, structure and DFT calculations of mononuclear cyclic (alkyl)(amino) carbene supported titanium(ii) complexes†
Abstract
The mononuclear cyclic (alkyl)(amino)carbene (cAAC) supported titanium(III) chloride complex [(cAAC)2TiCl3] has been synthesized by treatment of free cAAC with TiCl3(THF)3. Further reduction of (cAAC)2TiCl3 with potassium graphite (KC8) afforded the desired (cAAC)2TiCl2 complex, which features a small S–T energy gap. Both complexes were structurally characterized and represent the first cAAC supported Ti complexes.
